ABSTRACT

Objective:To compare the mid-term clinical outcomes between traumatic stiff shoulder and frozen shoulder after arthroscopic capsule release combined with subacromial space recovery.Methods:From January 2014 to December 2019, 55 patients were treated at Sports Medicine Center, The First Affiliated Hospital, Army Medical University for limited range of shoulder motion. Of them, 22 suffered from traumatic stiff shoulder (7 males and 15 females) (group A) and 33 from frozen shoulder (10 males and 23 females) (group B). All patients were treated with arthroscopic 270° capsule release combined with subacromial space recovery. Shoulder pain was evaluated by visual analogue scale (VAS) and shoulder function by Constant score before operation and at the final follow-up. The 2 groups were compared in improvements in flexion, abduction, external rotation and internal rotation of the shoulder.Results:No significant difference was observed between the 2 groups in gender, age, course of disease, preoperative internal rotation or external rotation of the shoulder ( P>0.05). Preoperative VAS score [2.5(2.0, 3.3) points] and Constant score [(33.7±9.6) points] in group A were significantly lower than those in group B [4.0(3.0,5.5) points and (45.8±12.3) points] ( P<0.05). No complication like infection or nerve injury was found during follow-ups. All the incisions healed at the first stage. The follow-up time averaged 37.0 months (from 20 to 79 months). At the last follow-up, VAS scores [1.0(1.0, 1.0) points and 1.0(1.0, 1.0) points] and Constant scores [(87.0±3.2) points and (85.7±4.3) points] for both groups were significantly improved compared with their preoperative values [2.5(2.0,3.3)分points and 4.0(3.0,5.5) points for VAS; (33.7±9.6) points and (45.8±12.3) points for Constant score] ( P<0.05). Compared with preoperation, the improvements at the last follow-up were 99.3°±19.9° and 83.3°±27.7° in shoulder anteflexion and 102.0°±21.5° and 83.9°±32.8° in abduction for groups A and B, with greater improvements in group A; the improvements in VAS score for groups A and B were 1.0(1.0, 2.3) points and 3.0(2.0, 4.5) points, with greater improvements in group B; the improvements in Constant score were (53.3±9.5) points and (39.8±12.9) points for groups A and B, with greater improvements in group A. The above comparisons all showed a significant difference between the 2 groups ( P<0.05). Conclusions:Arthroscopic 270° capsule release combined with subacromial space recovery can lead to good mid-term clinical outcomes similar for both traumatic stiff shoulder and frozen shoulder. However, the improvements in flexion, abduction and Constant score may be greater for traumatic stiff shoulder than for frozen shoulder.

ABSTRACT

Objective: To evaluate mid-term effectiveness of manipulation under anesthesia combined with arthroscopic capsular release and subacromial debridement for primary frozen shoulder. Methods: Between January 2013 and December 2017, 33 patients of primary frozen shoulder were treated with manipulation under anesthesia combined with 360° arthroscopic capsular release and subacromial debridement. There were 10 males and 23 females, aged from 37 to 65 years, with a mean age of 50.9 years. The affected shoulder on left side in 17 cases and on right side in 16 cases. The disease duration was 6-13 months (mean, 8.4 months). Before and after operation, the visual analogue scale (VAS) score was used to evaluate the shoulder joint pain, Constant score was used to evaluate the shoulder joint function, and the flexion, abduction, and external rotation of shoulder joint were recorded. The internal rotation function was assessed based on the vertebral plane that the thumb could reach after internal rotation of the affected shoulder joint (the rank of internal rotation vertebra). X-ray film was taken to measure the distance of the subacromial space. Results: There was no fracture or labrum tear in all patients, and all the incisions healed by first intention. All the 33 patients were followed up 20-31 months, with an average of 24.1 months. During the follow-up, there was no complication such as wound infection and nerve injury. At last follow-up, the range of motion of shoulder flexion, abduction, and external rotation, the rank of internal rotation vertebra, the VAS score, Constant score, and subacromial space were significantly improved when compared with preoperative ones ( P<0.05). Conclusion: Manipulation under anesthesia combined with arthroscopic capsular release and subacromial debridement can achieve a good mid-term effectiveness without complication for primary frozen shoulder.

ABSTRACT

Objective: To evaluate the mid-term effectiveness of arthrolysis and hinged external fixation for the treatment of stiff elbow caused by heterotrophic ossification. Methods: Between January 2014 and December 2017, 11 patients with stiff elbow caused by heterotrophic ossification were admitted. There were 9 males and 2 females with an average age of 32 years (range, 14-48 years), and left side in 6 cases and right side in 5 cases. The cause of stiff elbow included humerus fracture in 5 cases, ulna fracture in 2 cases, fracture of capitulum radii in 1 case, dislocation of capitulum radii in 1 case, terrible triad of the elbow in 1 case, and soft tissue injury in 1 case. The disease duration ranged from 7 to 18 months (mean, 11 months). Preoperative active range of motion of elbow was (19.6±17.5)° and Mayo score was 34.1±9.7. All patients received the treatment of arthrolysis and debridement of heterotrophic ossification lesion combining hinged external fixator, and active and passive rehabilitation with the help of hinged external fixator. The hinged external fixators were removed after 2 months. Results: All patients were followed up 13-36 months (mean, 19.1 months). All incisions healed by first intention, and no complication of infection or nerve lesion occurred postoperatively. At last follow-up, the results of X-ray films showed that no heterotrophic ossification recurred. The active range of motion of elbow was (116.4±16.6)° and Mayo score was 93.2±7.8, showing significant differences when compared with preoperative ones ( t=17.508, P=0.000; t=16.618, P=0.000). Conclusion: The application of arthrolysis and debridement of heterotrophic ossification lesion combining hinged external fixator can improve the elbow's range of motion significantly and obtain a good mid-term effectiveness.

ABSTRACT

Objective To analyze the clinical characteristics of respiratory involvement in relapsing polychondritis(RPC). Methods The clinical data of 38 patients with respiratory (larynx, trachea and bronchus) involvement in RPC were retrospectively analyzed. Results The incidence of respiratory involvement in patients with RPC was 51.35%(38/74), and the most common symptoms were cough, wheezing, chest tightness and dyspnea. The incidences of erythrocyte sedimentation rate (ESR) increasing, C- reactive protein (CRP) increasing, fibrinogen increasing, D- dimer increased and rheumatoid factor (RF) positive in patients with respiratory involvement were significantly higher than those in patients without respiratory involvement: 47.37% (18/38) vs. 30.56% (11/36), 52.63% (20/38) vs. 33.33% (12/36), 31.58% (12/38) vs. 25.00% (9/36), 21.05% (8/38) vs. 13.89% (5/36) and 36.84%(14/38) vs. 5.56% (2/36), and there were statistical differences (P<0.05). CT was the main method to discover the respiratory involvement, and MRI could detect early cartilage inflammation lesions. Laryngoscope and bronchoscope could early detect mucosa and cartilage damage. Pathology was given priority to lymphocytes and neutrophils infiltration. Some patients had epithelium metaplasia and even canceration. Primary treatment methods were glucocorticoids combined with immunosuppressant. Airway stenosis and infection was the main factors influencing the prognosis of patients. Conclusions The respiratory involvement is not uncommon in RPC, and early CT, MRI, laryngoscope and bronchoscope examination is an important means of early diagnosis.Early glucocorticoid combined immunosuppressive therapy is the key to achieve good prognosis.

ABSTRACT

BACKGROUND: Many studies have shown that different types of anterior cervical surgery in the treatment of two-level contiguous cervical disc herniation can obtain satisfactory results, but which method is the best has not yet reached a consensus. OBJECTIVE: To compare the efficacy and safety of three types of anterior cervical surgery for treating two-level contiguous cervical disc herniation. METHODS: We retrospectively analyzed clinical data of 62 patients with two-level contiguous cervical disc herniation who underwent anterior decompression and fusion. These patients were assigned to three groups. Bone graft group received anterior cervical discectomy with autogenous iliac bone graft fusion. Titanium mesh group received anterior cervical corpectomy with titanium mesh fusion. Cage group received anterior cervical discectomy with cage fusion. Fusion rate of bone graft and improvement of neurological function (Japanese Orthopaedic Association Scores) were evaluated and compared after treatment in the three groups. Cervical vertebra anteroposterior and lateral images were used to measure height of anterior and posterior margin of vertebral body and Cobb angle changes of fusion segment. RESULTS AND CONCLUSION: Al 62 patients were fol owed up and the fol ow-up time was ranged from 8 to 30 months. Operation time was significantly longer in the bone graft group than in the titanium mesh and Cage groups (P 0.05). The fusion rate of bone graft was higher in the bone graft group than in the titanium mesh and Cage groups (P 0.05). The increase in the height of posterior margin was higher in the Cage group than in the bone graft group and titanium mesh group (P 0.05). These findings indicated that the three kinds of fusion method for treating two-level contiguous cervical disc herniation could obviously lessen nervous systems and improve cervical vertebra functions. In the bone graft group, operation time was long. Intraoperative blood loss was more. Postoperative height loss of the posterior margin of the vertebral body was visible. Cervical lordosis could be easily induced. Compared with the bone graft group, titanium mesh and Cage groups could better maintain the height and curvature of the cervical vertebra, but the Cage group had apparent advantages.

ABSTRACT

Background Retinal neovascular diseases affect visual function.Although many drugs have been used to manage the visual diseases,their effectiveness is less than satisfactory.Studies showed that ursolic acid has multiple biological effects including anti-vascularization.However,the effect of ursolic acid on retinal neovascular diseases is unclear now.Objective This study was to observe the inhibitory effect of ursolic acid on the high oxygen-induced mouse retinal neovascularization after intravitreal injection.Methods Sixty clean 7-day-old C57BL/6J mice were divided into the blank control group,PBS control group,positive control group (triamcinolone) and low,moderate and high dose (1.5,3.0 and 6.0 μg) ursolic acid groups randomly.The blank control group mice were raised in normal environment,and the mice from other groups were fed in the environment with O2 concentration at (75±2)% for 5 days together with the maternal mice.The mice then were back to the normal air environment to induce retinal neovascularization.Then,the drugs were intravitreally immediately injected in the mice of the different groups.The mice were sacrificed at the 17-day old for the preparation of retinal sections.Retinal new blood vessel was examined by haematoxylin and eosin stain under the light microscope,and the number of vascular endothelial cell nucleus breaking the inner limiting membrane was counted.The gene expressions of vascular endothelial growth factor (VEGF),cyclooxygenase-2 (COX-2) and matrix metalloproteinase-2 (MMP-2) in the mouse retinas were quantitatively assayed using reverse transcription PCR.Results The number of endothelial nuclei newly-generated vessel breaking internal limiting membrane in the mice of PBS control group was (18.65±3.24)/field,which was more than (0.78±0.11)/field of the blank control group obviously (t =2.24,P<0.05).The number of endothelial nuclei newly-generated breaking internal limiting membrane in the moderate-or high-dose ursolic acid group was less than that of moderate group obviously,it was statistically significant(P<0.05).The number of vascular endothelial cell nuclei breaking internal limiting membrane in high high-dose group was (13.32 ± 1.87)/field and (8.93 ± 1.09) /field,showing significant decreases in comparison with the PBS control group and low-dose ursolic acid group (18.65±3.24)/field (15.44±2.02)/field (all at P<0.05).However,no significant difference were seen in the number of new vascular endothelial cell nucleus between the high-dose ursolic acid group and the positive control group(9.14±1.13)/field (t=1.17,P>0.05).The relative expressions of COX-2 mRNA,VEGF mRNA and MMP-2 mRNA in the mouse retinas were higher in the PBS control group than those in the blank control group (t =13.45,12.49,14.32,all at P<0.05),and those in the moderate-dose or high-dose ursolic acid group were lowed in comparison with the PBS control group and the low-dose ursolic acid group (all at P<0.05),but there were no significant differences between the high-dose ursolic acid group and the positive control group (all at P>0.05).Conclusions Ursolic acid can suppress retinal neovascularization by down-regulating the expressions of VEGF,COX-2 and MMP-2 in oxygen-induced retinopathy of mouse in dose-dependent manner.

ABSTRACT

Objective To find new methods to control the pollution of dye,the law of adsorption and adsorption kinetics of vat blue RSN by amidoxime fiber were studied. Methods The amidoxime-Fe(Ⅲ) adsorption fiber was made from PAN fiber containing amidoxime groups reaction with Fe3+. The adsorption of vat blue in the aqueous solution on the amidoxime-Fe(Ⅲ) adsorption fiber was studied. The reaction order was determined by infinitesimal calculus,based on the relationship between the adsorption time and the concentration of vat blue. The activation energy was obtained by the rate constant of different temperature and the Arrhenius equation. Results The results of adsorption showed the optimal condition:pH was 10.5,the temperature was 45 ℃ and adsorption time was 80 min. The absorption was accorded with the Freundlich isotherm and the character of the first-order reaction. Conclusion The process of vat blue RSN adsorption by amidoxime fiber is simple and the raw materials of amidoxime fiber is very cheap,so it may be expected to apply to the industrial wastewater treatment

ABSTRACT

Objective To evaluate the effect of intravascular occlusion for carotid cavernous fistula (CCF) by analying the clinical features of CCF. Methods Twelve cases with CCF were analysed on their medical histories, clinical features in the eyes, clinical examinations and the therapeutic effects of balloon occlusion in internal carotid artery.Results Ten cases were treated successfully(83.33%), in which 2 cases were treated once more. There was no operation complication. The visual acuity of one case increased from no light perception to finger movement within 1 week preoperatively. The visual acuity of 10 cases improved 1~4 lines (Snellen chart). Some clinical symptoms and signs such as the lid, conjunctiva swelling, diplopia, the movement of eyeball and retinal hemorrhage were decreased remarkably. Carotid fistula of 12 cases with CCF were found to be occlusioned by digital subtraction angiography after operations.Conclusion The early diagnosis and treatment for CCF are necessary. Color doppler flow imaging, CT and DSA are useful examination methods for diagnosis of CCF. Intravascular occlusion is the best therapeutic method for CCF nowadays.
